Description

Technical Field

[0001] The present application relates to a push-type unlocking handle, belonging to the technical field of vehicle locks. Background Art

[0002] There are many handles used with snap-on locks on engineering vehicles, but since the rotation direction of the lock core assembly is fixed, the locks on engineering vehicles can only be unlocked in one direction after installation. This has little impact on most usage environments, but for some narrow and special environments, the handles and snap-on locks of the above structure may be unable to open or difficult to open. Utility Model Content

[0003] In view of this, the present application provides a push-type unlocking handle, which not only enables the key to open the handle in both clockwise and counterclockwise directions, meeting the installation environment requirements of different handles, but also gives the handle a larger telescopic stroke.

[0004] Specifically, the present application is implemented through the following scheme:

[0005] A push-type unlocking handle comprises a handle and a lock core assembly.

[0006] The lock core assembly is installed in the handle through the lock sleeve. A connecting flat position is arranged at the end of the lock core assembly. A connecting shaft is arranged at a position corresponding to the connecting flat position. A connecting groove matching the size of the connecting flat position is arranged on the connecting shaft.

[0007] The other side of the connecting shaft is connected to a connecting piece, and the connecting piece is provided with retaining ribs of different lengths, the retaining ribs are nested in the fixed pressing plate, the fixed pressing plate is fixedly connected to the handle, and a spring is provided between the fixed pressing plate and the connecting shaft.

[0008] An adjusting screw is arranged at the end of the connecting shaft.

[0009] In the above device, a split connection unit is formed by the lock sleeve, the connecting shaft and the connecting piece, and the connection between the lock core assembly and the connecting shaft is realized by means of the cooperation between the connecting groove and the connecting flat position. When it is necessary to adjust the rotation direction of the key, it is only necessary to adjust the installation direction of the lock core assembly to realize the change of the forward and reverse directions. The adjusting screw lifts the buckle to complete the unlocking. The stop ribs of different lengths are nested with the fixed pressure plate to realize the adjustment of the distance between the connecting shaft and the fixed pressure plate, thereby changing the stroke of the handle.

[0010] Further, as a preference:

[0011] The outer wall of the lock sleeve is provided with a plurality of positioning strips to facilitate the installation of the lock sleeve. More preferably, the outer wall of the lock sleeve is evenly distributed with 2-4 positioning strips.

[0012] The connecting shaft and the connecting piece are an integrated structure.

[0013] The connector is provided with two stop ribs, namely a long rib and a short rib. The corresponding fixed pressure plate is provided with a sliding groove. The long rib is embedded in the sliding groove, which is the maximum distance between the connecting shaft and the fixed pressure plate to achieve stop. The lock core assembly is rotated, and the connecting shaft and the connector are driven to rotate through the connecting flat position until the short rib corresponds to the sliding groove. Then the handle can be pressed, and the spring is compressed and deformed until the short rib is embedded in the sliding groove. At this time, the distance difference between the long rib and the short rib constitutes the handle stroke. When no force is applied, the spring recovers its deformation, pushing the connector away from the fixed pressure plate until it returns to its original position.

[0014] A first cover plate is disposed on the outer periphery of the fixed pressure plate to seal the fixed pressure plate. Preferably, the first cover plate is a sealing gasket.

[0015] The other end of the handle is provided with a second cover plate to seal the handle. Preferably, the second cover plate is a sealing gasket. The upper and lower ends of the handle are both water-prone points, and sealing gaskets are provided at these positions to seal and prevent water.

[0016] A sealing ring is arranged between the lock sleeve and the lock core assembly. The lock core assembly is a point where water easily enters. The sealing ring is used to seal the connection between the lock sleeve and the lock core assembly. At the same time, the lock sleeve is also subjected to the pushing force of the spring, so that the sealing ring is in a compressed state between the lock sleeve and the handle.

[0017] A sealing ring is arranged between the lock sleeve and the handle. The connection portion between the lock sleeve and the handle is a point where water easily enters. The lock sleeve is sealed by the sealing ring. At the same time, the lock sleeve is also subjected to the pushing force of the spring, so that the sealing ring is in a compressed state between the lock sleeve and the handle. The sealing ring at this location also plays a buffering role, preventing the handle and the lock sleeve from hard collision, thereby achieving a silent effect.

[0018] A spring washer is arranged on the adjusting screw.

[0019] The fixed pressing plate is provided with a limiting ring, and the limiting ring matches the size of the spring to achieve the limiting of the spring.

[0020] The above solution not only enables fast clockwise and counterclockwise adjustment of the lock core assembly, but also achieves multi-level waterproofing, which is safe and convenient for outdoor use. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The embodiment of the present application provides a push-type unlocking handle for an engineering vehicle. The panel lock of the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0031] Figure 1 A diagram showing this embodiment.

[0032] A push-to-release handle, see Figures 1 to 4 , comprising a handle 1 and a lock core assembly 2.

[0033] The handle 1 includes an upper end and a lower end. A first cover plate 11 is installed at the upper end opening, and a second cover plate 12 is installed at the lower end. The first cover plate 11 and the second cover plate 12 can both use sealing gaskets to seal the upper and lower ends of the handle.

[0034] The lock core assembly 2, the lock sleeve 4, the connecting shaft 7, the connecting piece 5, the fixed pressure plate 13, and the first cover plate 11 are installed in sequence, wherein the lock core assembly 2 is installed from the outer end of the handle 1 through the lock sleeve 4, the lock core assembly 2 and the lock sleeve 4 are sealed by the first sealing ring 22, and the lock sleeve 4 and the handle 1 are sealed by the second sealing ring 23. The end of the lock core assembly 2 is a connecting flat position 21, and a connecting groove 71 is penetrated in the connecting shaft 7, and the connecting groove 71 matches the shape of the connecting flat position 21, so that the connecting flat position 21 is snapped into the connecting groove 71; the side of the connecting shaft 7 facing the lock core assembly 2 is a small end, and after installation, the end portion extends into the lock sleeve 4, and the other side of the connecting shaft 7 is a relatively large boss, on which a connecting piece 5 is arranged, and the surface of the connecting piece 5 is arranged with a long rib 51 and a short rib 52, and the fixed pressure plate 13 is fixed to the handle 1 by a self-tapping screw 15, and a sliding groove 14 is arranged on it, and the sliding groove 14 matches the specifications of the long rib 51 and the short rib 52. A limiting ring 16 is provided on one side of the fixed pressure plate 13 facing the connecting member 5, a spring is sleeved on the connecting member 5 between the fixed pressure plate 13 and the boss of the connecting shaft 7, and one end of the spring 6 is limited by the limiting ring 16. An adjusting screw 3 is connected to the end of the connecting member 5.

[0035] In the above device, the lock sleeve 4, the connecting shaft 7 and the connecting member 5 form a split connection unit, and the connection between the lock core assembly 2 and the connecting shaft 7 is realized by means of the cooperation between the connecting groove 71 and the connecting flat position 21. When it is necessary to adjust the rotation direction of the key, it is only necessary to adjust the installation direction of the lock core assembly 2 to realize the change of the clockwise and counterclockwise directions, and the adjusting screw 3 lifts the buckle to complete the unlocking; the stop ribs of different lengths are nested with the fixed pressure plate to realize the adjustment of the spacing between the connecting shaft and the fixed pressure plate, thereby changing the stroke of the handle: when the long rib 51 corresponds to the position of the sliding groove 14, it is the maximum distance between the connecting shaft 7 and the fixed pressure plate 13, and the embedding of the long rib 51 can realize the stop; the lock core assembly 2 is rotated, and the connecting shaft 7 and the connecting member 5 are driven by the connecting flat position 21 to rotate until the short rib 52 corresponds to the sliding groove 14, then the handle 1 can be pressed, and the spring 6 is compressed and deformed until the short rib 52 is embedded in the sliding groove 14. At this time, the distance difference between the long rib 51 and the short rib 52 constitutes the handle stroke. When the force is no longer applied, the spring 6 recovers its deformation and pushes the connecting member 5 away from the fixed pressure plate 13 until it returns to its original position.

[0036] Among them, in the above scheme, the outer wall of the lock sleeve 4 is provided with 2 or 4 positioning strips to realize its positioning and fixed angle rotation relative to the handle 1.

[0037] The above solution not only enables fast clockwise and counterclockwise adjustment of the lock core assembly, but also achieves multi-level waterproofing, which is safe and convenient for outdoor use.
